Abstract

Objective: To evaluate the application of magnetic resonance imaging (MRI) in the diagnosis of the neuropathy by nerve III palsy. Methods: Cross-sectional descriptive analysis was performed on 75 patients with paroxysmal cataract, beneficed une cerebral IRM with and without Gadolium. Results: 48 patients had nerve damage on MRI. Of these, 9 patients had lesion in brain sterm, 22 had lesion of the segment in the cavernous sinus, and 11 had a lesion of Cisternal segment. Inflammation and infection of nerve III were seen in 28 patients. There were 10 patients with abnormalities of the pupil, suggesting the cause of compression. 6 cases with thickening and increased signal of the III line and the appearance of infiltration. 27 patients with a history of diabetes mellitus, vascular disease, but complete magnetic resonance, with no enhance of the nerve III on MRI. Conclusions: Patients with no history of diabetes or vascular disease, only acute third nerve palsy should remainwho exhibit pure mesenteric lymphoma should still receive MRI as a baseline unless, of course, the patient with the symstomes of hemorrhage meningeal, to exclude the cause of infiltration or intracerebral lesion. Patients with a history of diabetes mellitus or vascular disease, suggest a prevalence of ischemic infiltration very common, particularly in elder patients, but should still receive conventional cerebral apoplexy if disease doesn’t improve after 3 weeks.
